S3 or S6 Welding Wire for line boring?

admin

Not sure if this is the right forum but here goes. Recently purchased a York line boring machine. Also use an automatic bore welder to build up the bore. I have read that S3 welding wire is easier to grind that S6 welding wire. So I am wondering if S3 wire is easier to machine or is there no difference?Golf Supplies | Golf Carts | Yamaha golf cars

Reply:Well you have the same bore welder & boring system I have been helping my friend try to get up & running. The welding when it was demoed looked like it would be a piece of cake but has turned out to be anything but. Using the same brand & number inverter as the demo + the respooled wire they recomended we can not get the same weld quality as the demo, as a matter of fact some times it is just plain Ugly. Some times fairly decent but cant do decent or good consitantly. Any tricks up your sleeve about this?? For some reason it also looks like a wire feed issue at about the 10-2 oclock area. The mfg. has been good with advise & the test coupon they sent done on the machine is perfect. we have both been doing wire welding for a looong, loooong time.
Reply:We have been having the same trouble. It seems to work better after I clean the liner with brake cleaner and the tip is wore out a little. If we put a new tip in it will weld a few minutes and start messing up. Its almost like the tip is getting hot and swelling to the point the wire has trouble feeding. We can take a new tip and use a torch tip cleaner and make the hole a little bigger and it helps. I think the biggest problem is if it has the slightest feeding issues it messes up. I also try and use those wire cleaner pads whenever possible. I am using .030 wire now but I'm going to try .035 to see if that helps with feeding issues. I tried .045 once.....it wasn't pretty. Are you using a 75/25 mix?Golf Supplies | Golf Carts | Yamaha golf cars
Reply:Thanks for the tip about the tip. We will try that. Yup, 75/25 & .035 s-6 wire. If I can get my friend to just turn one dial at a time when we are trying to dial it in we might have better luck but no he has to turn both wire speed & voltage at the same time. Makes it hard to sort out what helps & what doesnt. Right now he seems to be discusted with the whole thing or possibly a little buyers remorse. I try to gently push him in to setting up a stand simaler to the demo stand the sales man had to tune the welding in before another job comes up, the last one turned into a fiascoe of late nights and a very irrate customer. Funny thing he wanted to dig with his backhoe bucket not have some yahoos trying to sort the bore welder out on it.
Reply:If all your doing is buckets and arms and such, why not do it like they do in the factories that build the crap. When they screw up they just put the copper backer on it and weld it by hand. I've done a bunch that way when the CNC or operator would screw up. CNC just runs a clean-up pass and then bore it like normal. They've welded complete holes shut that were too far off...just machine a new one. The bore welder rarely left the wall where it was kept...just wiped it down once in a while so it didn't look like just another piece of scrap...lol.Anything worth doing is worth doing RIGHT
Reply:We have had some recent success with the bore welder and I thought I would pass the info along. I cut the sheilding gas nozzle on an angle so it can be closer to the peice being welded. Its been working pretty well for us. You have to screw the nozzle in tight and mark it with a black marker where on what angle you need. Then cut or grind the nozzle on an angle like the attached pics below. I know its crude but its working for us.And a few other tips.1. Make sure the liner is a straight as possible and not looping.2. Use those wire cleaner pads that you place just before the drive rolls on the feeder.3. Keep the nozzle as close as possible to the work peice.

Reply:Thanks for sharing the tips Muppethunter, you may have saved hours or days of fustration for us and there has been to much of that already. With the tips you have passed along I think i can get him to take the bore welder out of the box and try again. Once again, THANKS.

Reply:Thanks again. What are you useing for a power source ? The xmt304 ? My friend is now convinced it needs to be a pulse machine so every thing is at a stand still untill an adapter can be found to use a mp 350 lincoln he has on try out.

Reply:well, muppethunter I got a call 15 minuetes ago and just reread your tips . We are going to try again in about an hour and I will see if I have enough influence to get some of them used.   Once again thanks,  Paul
Reply:lars, we line bore 20-30 machines a year. i usually do the facial welds on the tractors and an outside shop does the actual inner welding and boring. having spent many of hours with their field machinist, here's his recommendation. use a S6 wire uncoated. the brass coating flakes off in minute particles and these clog the liner and tips. the 11-1 position is where the wire is rolling itself inside the liner and tip. spray the nozzle with anti-spatter to keep the nozzle clean. keep the liner as strait as possible. also make some cardboard cut-outs to ride on the shaft to keep any chips or spatter from the shaft and drive units. try using an oversized tip. he runs a .035 wire but runs a .039 tips. the slight swelling will tend to bind up the wire.keep notes. i have notebooks full of everything we bore. weld parameters, dimensions, everything. notes and more notes.oh yeah, for the love of all things welding. steam clean and use some kind of chem cleaner in the bore. i have experimented with a rosebud and steam genie to attempt to get the grease out. acetone or varsol or lots of brake cleaner. years of old grease just digs into the pores of the metal and causes lots of cussing and thrown chipping hammers when the laborers don't clean the machine the way i want.Last edited by backuproller; 11-09-2007 at 06:29 AM."Retreat hell, were just fighting in the other direction"Miller Trailblazer 302, Extreme 12 VS, Dimension 400, Spectrum 375, HF 251D-1, Milermatic 251 w/ spoolgun  Hypertherm 1000Lincoln sp 1702000 F-450 to haul it
Reply:Hey, thanks backuproller. Our session with the bore welder actually went pretty good yesterday, my friend had been working with it when he was alone in the shop and had calmed down a lot since our last session. All and all I think he could take on a job with it now and have decent results.    Paul

Reply:Just looking for some one with experience with bore welding to pass along any tips, tricks, and most of all what machines the prefer. Would like to chat about every thing from the power source they use, to, if they do this in the shop or field?
